IMPROVEMENT IN TOGGLE-PINS' FOR NAIL-MACHINES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern: Be it known that I, \VILLIAM H. RIDLEY, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvemeut-in Toggle-Pin for Nail-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.

The nature of my invention consists in a toggle-pin. construotedin three parts, so arranged with relation to each other that it can be 'adj usted to the wear of the parts of a nail-cutting machine used for cutting and heading the nail.

To enable others skilled in the art to make and use my invention, 1' will proceed to describe its constructionand operation.

In the accompanying drawing, my specification-- Figure 1' represents the position of the toggle-pin with relation to the cutting and heading parts of a nail-cutting'machine.

Figure 2 is'a vertical section of the toggle-pin.

The toggle-pin is used for transmitting motion from the cutting-head to the heading-jaw or die of a'rrailwhich forms part of cuttingmachine, and when it becomes too short by wear (which is often the case) it has to be removed from t-he-machiue,and;bya forging and fitting process, adj ustedio the parts of the machine to which it belongs; fliis forging and fitting process is a source of.

without removing the pin from the machine, and with out loss of time, and requiring comparatively no labor.

In the accompanying drawing A represents the cutting-head of a nail-cutting Ina-- chine; the lever D of which is attached to a wheel, 0, in the ordinary manner. B represents the lever of the heading-jaw or die.

G represents the toggle-pin which is used for transmitting motion from the cutting-head to the headingjaw.

This toggle-pin I make in three parts, viz., the male part f, female part j, and'clamping-nut h, the construction of which is clearly shown in fig. 2, and the operation of which will readily b'ennderstood by the skillful mechanic, who will'also understand the mode or manner of using and adapting it to its ofiice in a nail-cutting machine.

Having thus described the nature, use, and advantage of my improvement,

hat I claim as of my invention is A toggle-pin, constructed substantially as hereinbefore described, and for the purpose set forth.-
